Radiator Fan

[Max Hoepli]

Fan switch is meant by Thrrmoswitch at the lower right rear part of rad?

I drove the car on the highway, temperature always at about 75C, when I
stopped I saw coolant leaking at auxillary coolant pump, next to fan motor
motor and in front of brake master cylinder. Not leaking where hose is
joining anywhere.
Ideas?

Max

It shouldn't.  You have numbers on your gauge?  The tstat opens at 87 or 
92.  The fan should kick in in the high 90s, I think.

So perhaps your fan switch is bad?  Or the relay... or the wiring...

Testing the switch is "easy" if you don't mind dumping your coolant and 
you are permitted to perform scientific experiments on the kitchen 
stove.  And have an ohm meter.  And a decent meat thermometer.
